As you seeing that, when i take my cursor on StackOverflow icon, it shows 1577 reputation points,
but it is actually 1584 this time. (it happens Not for only SO icon, but for all the associated accounts)

I have checked this by refreshing a page many times and even also loggin out many times, as i think it
may be updated soon.

So, for updation of SO reputation, Meta-SO reputation, SuperUser reputation point to the
area51 or any inter-related site, what is the actual delay time for updation? i think this should be changed to
the associated account quickly as and when the reputation point is updated.
